tutorial python examples/vww.py not work in python 3.8 #89

Open xpsheng opened 1 year ago

xpsheng commented 1 year ago

Using Windows WSL setup, environment info like below: Ubuntu 20.04.3 LTS (GNU/Linux 5.10.16.3-microsoft-standard-WSL2 x86_64) python 3.8.10 by default.

Follow the related setup from tutorial https://github.com/mit-han-lab/tinyengine/tree/main/tutorial/inference There got following error. Could tinyengine development pointout what's the problem there? or current setup verify/support only in python 3.6 not for other newer version?
